Just as a funny side note, I remember getting Portuguese 308 ball delivered to my house for $120/1000. That's 12 cents a pop...literally.

How about .357 magnum?

Well then… you are straddling the fence, needing both "mass quantities" (plinking) and "precision" (non-magnum rifle cartridges that shoot flat and still reach out at a distance).

As a competent reloader, I would approach "mass quantities" with a progressive reloading press (e.g., pick your price point with the Dillion line https://www.dillonprecision.com/ ), but approach "precision" with a high-end single-stage coaxial reloading press (e.g., Forster https://www.forsterproducts.com/ ) and a bevy of high-end (viz., expensive) accoutrements (e.g., magnetic restoration scale https://www.accurateshooter.com/gear-reviews/sartorius-magnetic-scale-is-fast-ultra-precise/ ).

In the decades when I was active in "3-Gun" competition, I typically shot 1,000-4,000 rounds per month in practice. I decided to reduce my costs, so I scrounged my brass and was gifted brass and reloaded it all. It took me about 2 weeks of evenings to reload about 2,000 rounds (clean, lube, re-size, case-length trim, de-lube, inner chamfer, outer chamfer, prime, charge, seat projectiles, box). I tallied my receipts and discovered that for giving up two weeks of evenings I had saved—wait for it—about $50 for the 2,000 rounds compared to the cost of buying milspec in bulk.

Speaking for myself, It was worth $50 for me to re-capture 2 weeks of evenings with my family. I gave my Dillon to a buddy and ever since, for "mass quantities," I shop price commercially and carefully (https://ammoseek.com/ http://www.gunbot.net/ and am on several email lists for bulk ammo distributors).

XLR, however, is entirely different. With one possible exception (vide infra), nothing commercial "Match" shoots as precisely as my handloads, not Federal Gold Medal Match, not Black Hills Match, not even Lapua Match. I have selected components, powders, projectiles, charge weights, and "jump" based on OCW ladders proven at distance. My reloads outperform them all… except…

…the Berger line of ammunition (formerly Applied Ballistics Munitions), https://bergerbullets.com/product-category/ammunition/, the brainchild of the well-known ballistician Bryan Litz. For the life of me I do not understand how they mass produce ammunition that shoots as well as my flake-by-flake meticulous handloads. That said, my reloads beat the very high price of the Berger ammunition—for example, .338 Lapua with Berger's 300gn Hybrid OTM Match runs about $5/rd, (Lapua 300's are about $7/rd) not quite twice what my equivalent reloads cost. What is your time worth?

I hope this has been helpful.

The comic is really well done, so well done that the artists went to jail.

Point of clarification: I do not spurn progressive loaders because of any inherent inability to produce accurate ammo.  I shy away from progressive loaders when loading for service rifles (e.g., M1 Garand, M14 clone, AR-15), all of which are gas guns and have floating firing pins, wherein a single primer seated slightly proud could result in an out-of-battery ignition, or a slight overcharge in powder could damage a gas system. Not good.  I tend to hand-prime and individually weigh the charge for each cartridge when loading for service rifles.  This isn't to say that a Dillon (or other progressive presses) need be avoided; I just choose for my own reasons to use a single-stage press, and I don't load enough handgund ammunition to justify getting a second progressive press.  YMMV.  

Ahhhhh!
I prime cases by hand.
